量詞：一聽； cross-sensitization, cross-tolerance, cross-dependence, reward

 If you consider that the added sugar in a single can of soda might be more than most people would have consumed in an entire year, just a few hundred years ago, you get a sense of how dramatically our environment has changed. 如果我們思考一下，今天一聽碳酸飲料里含有的添加糖分，可能高於幾百年前多數人一整年消耗的糖分，就能明白我們周圍的環境發生了多麼巨大的改變。http://cn.nytimes.com/opinion/20141225/c25dinicolantonio/zh-hant/

很久沒聽到/讀到"聽"當量詞，所以翻字典才想起。

聽
量詞。計算罐頭食品的單位。為英語 tin的音譯。如：「一聽奶粉」。

台灣現在的用法可能偏向"一罐"。

----這篇文章下文的翻譯也很有意思，一般人不易懂"交叉"，所以要查字典：(換句話說，可考慮加注)。

cross-sensitization,

n a phenomenon in which a person becomes sensitized to substances different from the substance to which the person is already sensitized.

cross-tolerance,

a tolerance to other drugs that develops after exposure to a different agent. An example is the cross-tolerance that develops betweenalcohol and barbiturat

/cross-tol·er·ance/ (kros?tol-er-ans) extension of the tolerance for a substance to others of the same class,even those to which the body has not been exposed previously.

Cross dependency is an associated issue that some addicts may experience where their dependence on a drug can be alleviated by the use of another drug.

 In animal models, sugar produces at least three symptoms consistent with substance abuseand dependence: cravings, tolerance and withdrawal. Other druglike properties of sugar include (but are not limited to) cross-sensitization, cross-tolerance, cross-dependence, reward, opioid effects and other neurochemical changes in the brain.在動物模型中，糖分至少產生了三種與物質濫用和依賴相吻合的癥狀：渴求感、耐受性、戒斷癥狀。糖分其他與毒品相似的特性還包括（但不限於）交叉敏化、交叉耐受性、交叉依賴性、獎賞效應、阿片效應，以及大腦中的其他神經化學變化。

在動物實驗中，動物對糖的感受就像一種毒品，而且可能會對糖產生依賴。一項研究顯示，如果提供了選擇，大鼠在實驗室的環境中會選擇糖而不是可卡因，因為前者的獎賞效應更強，即糖帶來的「興奮感」有着更高的愉悅度。
